Answer / rakesh
It is sometimes easier to deal with primitives as objects.
Moreover most of the collection classes store objects and
not primitive data types. And also the wrapper classes
provide many utility methods also. Because of these resons
we need wrapper classes. And since we create instances of
these classes we can store them in any of the collection
classes and pass them around as a collection. Also we can
pass them around as method parameters where a method expects
an object.
